Operating microscope light-induced chorioretinal phototrauma

Since the widespread use of operating microscopes and artificial intraocular lenses in the early '80s, photoretinitis of the macula and paramacular area has been a well-documented clinical entity. A case is reported of a unilateral paramacular chorioretinal phototrauma after cataract extraction and posterior chamber intraocular lens implantation. Indocyanine-green angiography (ICG-A) demonstrated the atrophy of the choriocapillaris, which was seen as a hypofluorescent area

UNILATERAL CYTOMEGALOVIRUS RETINITIS IN A PATIENT WITH IMMUNOGLOBULIN G2 DEFICIENCY.

A benign course of cytomegalovirus (CMV) retinitis is reported in a young patient with selective immunoglobulin G2 (IgG2) deficiency, after corticosteroid treatment for inflammatory pulmonary disease. IgG2 deficiency is a specific disorder of humoral immunity and has little to do with defense against viruses. This case suggests that CMV retinitis can occur in patients with IgG2 deficiency, who have received steroids in a presumedly nonimmunosuppressive dose for associated respiratory disease
